abstract = {Studies suggest that the affective response is impaired in
both schizophrenia and adolescent offspring of schizophrenia
patients. Adolescent offspring of patients are
developmentally vulnerable to impairments in several
domains, including affective responding, yet the bases of
these impairments and their relation to neuronal responses
within the limbic system are poorly understood. The amygdala
is the central region devoted to the processing of emotional
valence and its sub-nuclei including the baso-lateral and
centro-medial are organized in a relative hierarchy of
affective processing. Outputs from the centro-medial nucleus
converge on regions involved in the autonomous regulation of
behavior, and outputs from the baso-lateral nucleus modulate
the response of reward processing regions. Here using fMRI
we assessed the intra-amygdala response to positive,
negative, and neutral valenced faces in a group of controls
(with no family history of psychosis) and offspring of
schizophrenia parents (n=44 subjects in total). Subjects
performed an affective continuous performance task during
which they continually appraised whether the affect signaled
by a face on a given trial was the same or different from
the previous trial (regardless of facial identity). Relative
to controls, offspring showed reduced activity in the left
centro-medial nucleus to positively (but not negatively or
neutral) valenced faces. These results were independent of
behavioral/cognitive performance (equal across groups)
suggesting that an impaired affective substrate in the
intra-amygdala response may lie at the core of deficits of
social behavior that have been documented in this
population.},
